Directed IPX Packet
A valid directed IPX packet contains:
It might also include LLC/SNAP Headers and VLAN Tags. Since filtering this packet
relies on the flexible filters, which use offsets specified by the operating system
directly, the operating system must account for the extra offset LLC/SNAP headers and
VLAN tags.
IPv6 Neighbor Discovery Filter
In IPpv6, a neighbor discovery packet is used for address resolution. A flexible filter can
be used to check for a neighborhood discovery packet.
Wake-Up Packet Storage
The 82574L saves the first 128 bytes of the wake-up packet in its internal buffer, which
can be read through the WUPM after the system wakes up.
• The station's MAC address.
• A protocol type of 0x8137.
• an IPX node address that equals the station's MAC address.
